Andersen's Waterhog Grand Premier Entrance Mat has a beautiful and unique fan design that is great at removing dirt and water from the soles of shoes. The rubber-reinforced nubs hold their shape and won't flatten, even in high-traffic areas. Instead of a black rubber border, the Grand Premier has a border that is made of the same material as the mat. A water dam on the border of the mat keeps water and dirt from spilling onto your floors. The anti-static mats are safe to use in computer rooms and around electronic equipment. Choose from seven attractive colors and two backing styles. Your mat won't fade or rot because the fabric is made of a 36-ounce, polypropylene yarn that is 50 percent heavier than the Waterhog Classic Entrance Mat. To clean, just vacuum or hose off and hang to dry. Listed size is approximate.
